摘　　要：从噪声源的产生机理和相位噪声定义的角度出发,浅析线性电源及开关电源中的纹波抑制和噪声对微波光子链路的相位噪声指标的影响。针对在微波光子系统中运用较多的开关电源进行优化设计,并将优化前后的两组方案进行实验验证、测试两种情况下微波光子链路的噪声系数指标,得出结论,给微波光子链路系统的电源设计提供参考。From the point of view of the generation mechanism of noise source and the definition of phase noise,this paper analyzes the influence of ripple suppression and noise in linear power supply and switching power supply on the phase noise of microwave optical link.In order to optimize the design of switching power supply which used mostly in microwave optical link system,verify the two schemes before and after optimization by testing the phase noise of microwave optical link in two cases,then draw a conclusion,which provides reference for the power design of microwave optical link system.
